Python If with AND Operator - Examples

Python If AND

You can combine multiple conditions into a single expression in Python conditional statements like Python If, If-else, and Elif statements. This avoids writing multiple nested if statements unnecessarily, providing a cleaner and more readable approach.

Examples

In the following examples, we will see how we can use Python AND logical operator to form a compound logical expression within conditional statements.

1. Python If with AND Operator

In this example, we will learn how to use the AND logical operator in a Python If statement to join two boolean conditions into one compound expression.

We will demonstrate the advantage of the AND operator by first writing a nested if and then simplifying it into a single if statement, achieving the same functionality with fewer lines of code.

Python Program

a = 5
b = 2

#nested if
if a==5:
	if b>0:
		print('a is 5 and',b,'is greater than zero.')

#or you can combine the conditions as
if a==5 and b>0:
	print('a is 5 and',b,'is greater than zero.')

In the above example, we check whether a equals 5 and whether b is greater than 0. Using the AND operator allows us to combine both conditions into a single statement, reducing the need for a nested if.

Output

a is 5 and b is greater than zero.
a is 5 and b is greater than zero.

2. Python If-Else with AND Operator

In this example, we will use the AND operator to combine two basic conditional expressions in a Python If-Else statement.

Python Program

a = 3
b = 2

if a==5 and b>0:
	print('a is 5 and',b,'is greater than zero.')
else:
	print('a is not 5 or',b,'is not greater than zero.')

Explanation:

  1. If a is equal to 5 and b is greater than 0, the message is printed. Otherwise, the else block is executed.

Output

a is not 5 or 2 is not greater than zero.

3. Python elif with AND Operator

In this example, we use the AND operator to combine two basic conditional expressions in a Python elif statement.

Python Program

a = 8

if a<0:
	print('a is less than zero.')
elif a>0 and a<8:
	print('a is in (0,8)')
elif a>7 and a<15:
	print('a is in (7,15)')

Explanation:

  1. The first condition checks if a is less than 0. If a is not, it proceeds to the second condition, where we check if a is between 0 and 8 (exclusive). If that’s false, the third condition checks if a is between 7 and 15.

Output

a is in (7,15)

Summary

In this tutorial, we learned how to use the Python AND logical operator in Python conditional statements such as if, if-else, and elif statements. By using the AND operator, we were able to combine multiple conditions into a single expression, simplifying our code and making it more efficient.
